Current = (voltage) / (resistance)

The ends of the 10-ohm resistor are connected directly to both terminals of the battery.

So the voltage across the resistor is the voltage of the battery ... 120 V. None of that other stuff in the circuit has any effect on it.

Current = (120 V) / (10 ohms)

Current = 12 A . (B)

Answer:

B. 12.0A

Step-by-step explanation:

The circuit shown in the image is a parallel circuit which mean that the voltage of the source is equal across each resistance in the circuit because they are directly connected to the terminals of the voltage source.

The voltage across the 10 Ohms resistor is 120V

So, let's proceed to calculate the current

By using Ohm's Law


I=(V)/(R) \\I= (120.0V)/(10.0Ohm) \\I= 12.0A

12A is the amount of current flowing through the 10 ohms resistor.
